refactor(arena-two-pick): route entry/finish through InventoryService

Browse Source 
Replace RewardGrantService + ICurrencySpendService + IViewerEntitlements with
IInventoryService. tx.IsFreeplay replaces FakeEntitlements.IsFreeplay; debit
helpers take IInventoryTransaction. ComputePostStateRewardList deleted (replaced
by result.RewardList from CommitAsync). Update 5 test files to new 8-arg ctor.
